The thing is, you just can't go wrong in Paris. It's kind of pointless recommending any specific bistros as pretty much everywhere sells delicious, freshly-prepared food at fair prices. I'm sure there must be bad restaurants out there, but any bistro you wander into is almost guaranteed to be a winner. Ethnic food, too, is generally so much better cooked and more reasonably priced in Paris than in the UK. The best Thai meal I ever had was in Paris and cost around �6 for three courses.
